Looks like a feature...
To me!
(it's a "horizontal rule", also known as a line, which you can put in HTML as <hr> or in Lemmy comments using three dashes Edit: asterisks)
It can be either --- or *** according to join-lemmy
---
***
Yeah the dashes didn't work which is why I made the edit to the asterisks.
Both work for me
Edit: Interesting... Working now. Not sure what happened that first time.
